FIG. 4 is a partially cutaway sectional view as seen from the direction of the back surface 1c of the housing. In addition, about the same part as the washing-drying machine in a prior art example, the same code | symbol is attached | subjected and the description is abbreviate | omitted.

  As shown in FIGS. 1 to 4, a cylindrical water tank 3 elastically supported by a plurality of suspensions 2 is provided in the inside of the casing 1 constituting the main body of the washing and drying machine in the first embodiment. The suspension 2 absorbs the vibration of the water tank 3 during washing and dehydration.

  Inside the water tank 3, a cylindrical and horizontal axis type rotating tank 5 that accommodates the clothes 4 is rotatably provided and is driven to rotate by a drive motor 6. On the front surface of the housing 1, there are provided an opening 1a for taking in and out the garment 4 and a door 7 for opening and closing the opening 1a.

  The front side of the water tank 3 and the rotary tank 5 also have similar openings 3a and 5b, respectively. The opening 3a of the water tank 3 is connected to the opening 1a of the housing 1 in a watertight manner by an extendable bellows 8. ing. The bottom of the water tank 3 has a drain port 9 for discharging the washing water in the water tank 3 (FIG. 4), and is connected to a drain valve 10 and a drain hose 11.

The blower 12 constituting the blowing means is a circulation duct 15 provided on the outer peripheral surface of the water tank 3 so as to be positioned in a corner space (upper part of the housing 1) formed by the upper surface 1d of the housing 1 and the water tank 3. Is placed inside. The blower 12 communicates with the blower passage 20 formed on the back surface of the water tank 3, blows the air that has entered the blower passage 20 in the direction of the arrow b (FIG. 3), and enters the rotary tank 5 from the air supply port 14. Supply. The air that has passed through the rotary tank 5 and has exited from the exhaust port 16 provided at a location close to the highest level of the water tank 3 is provided in the circulation duct 15 by the blower 12 so as to be positioned at the upper corner in the housing 1. Inhaled from the suction port 15a.

  A water-resistant heating heater 31 (heating means) having a well-known configuration is provided in the vicinity of the air supply port 15 b in the circulation duct 15. Further, between the blower a 12 and the heating heater 31 in the circulation duct 15. A water supply hose 18 and a water supply valve 17 which are tap water supply means are provided in the air passage. In addition, a valve 32 (blocking means) that suppresses or prevents water from entering the circulation duct 15 is provided at the air supply port 15 b of the circulation duct 15. The valve 32 is driven by driving means 32a such as a motor.

Furthermore, the rotating shafts of the water tank 3 and the rotating tank 5 are inclined at about 30 ° with respect to the horizontal, so that washing water is collected at the corners of the water tank 3 so that washing and rinsing can be performed with as little water as possible. . The inclination angle of the water tank 3 and the rotary tank 5 is not limited to 30 °, and is preferably in the range of about 0 to 30 ° in consideration of the amount of water used and washing efficiency.

  The operation of the washing / drying machine configured as described above will be described.

In the cleaning process, water is supplied into the water tank 3 by opening the valve 32 and opening the water supply valve 17 with the drain valve 10 closed. Then, as shown in FIG. 2, water is supplied into the water tank 3 until a predetermined water level is reached, and in parallel with this, the heater 31 is energized to warm the cleaning water.

When a predetermined amount of water is supplied into the water tank 3, the valve 32 is closed and the drive motor 6 is driven to rotate the clothes tank 4 and the rotating tank 5 containing the cleaning water to perform cleaning .

Therefore, washing is performed with warm water, and the dirt removal effect is superior to that of water.

When the above-described cleaning process is completed, the process proceeds to a rinsing process. Also in this rinsing step, the heating heater 31 is energized to warm the rinsing water as in the above-described washing step, hot water is supplied into the water tank 3, the valve 32 is closed, and then the rotary tank 5 is rotated. The clothes 4 are rinsed.

  Since such rinsing is also performed in warm water, the detergent is also efficiently dissolved in warm water, and the rinsing efficiency can be performed in a shorter time than in the case of water.

  Furthermore, when the above-described rinsing process is completed, a dehydrating process for the garment 4 is performed. In this dehydration step, the drain valve 10 is opened to drain the water in the water tub 3 to the outside of the washing and drying machine, and then the rotating tub 5 containing the clothes 4 is rotated at a high speed in one direction by the drive motor 6 to obtain the centrifugal force. To dehydrate.

  And when the above-mentioned dehydration process is completed, it will move to the drying process shown in FIG. In this drying process, the blower 12 is operated while the valve 32 is kept open and the heater 31 is energized. Further, the water supply valve 17 and the drain valve 10 are opened, and the state where tap water is supplied from the water supply hose 18 into the circulation duct 15 and discharged from the drain port 9 is continued. Further, the rotating tub 5 is rotated by a drive motor 6 and the clothes 4 are stirred up and down.

Therefore, warm air is supplied into the water tank 3 and the rotating tank 5 from the air supply port 15 b of the circulation duct 15, and the warm air blown into the rotating tank 5 takes away moisture when passing through the gaps of the clothes 4. In the wet state, the air passes through the exhaust port 16 of the water tank 3, passes through the blower 12 from the suction port 15 a, and reaches the tap water supply position in the circulation duct 15.

  When the wet warm air comes into contact with tap water poured into the circulation duct 15, sensible heat and latent heat are deprived and dehumidified, and separated into dry air and condensed water. This dry air is heated again by the heater 31 to be heated and supplied into the water tank 3 and the rotary tank 5 and circulates in the above-described flow to dry (dehumidify) the clothing 4.

  And if a drying process is complete | finished, the rotation tank 5 will be stopped and the water supply valve 17 and the drain valve 10 will be obstruct | occluded.

As described above, in the first embodiment, the formation of warm water and the formation of warm air are performed in order to improve the efficiency of cleaning and rinsing, and the heating heater 31 is energized to improve the efficiency of drying. Therefore, it is not necessary to provide a dedicated heater for each, and a configuration excellent in compactness and low cost can be achieved.

Further, since the valve 32 (blocking means) for stopping the flow of the fluid in the washing process and the rinsing process is provided in the circulation duct 15, entry of lint (lint) into the air passage is suppressed, and the heater 31 for heating Lint entanglement (adhesion) can be suppressed. Further, the closing of the valve 32 during the washing process and the rinsing process suppresses the growth of bubbles in the circulation duct 15 and, as a result, prevents corrosion of the components in the circulation duct 15. It improves the performance.

  Further, since the water supply valve 17 is disposed in the circulation duct 15 between the blower 12 and the heating heater 31 so that the water supply from the water supply valve 17 is applied to the heater 31, the water supply valve 17 adheres to the heater 31. The lint can be removed at the time of water supply, damage to the heater 31 can be suppressed, and reliability and durability are improved.

  In addition, since the rotation axis of the rotating tub 5 is inclined in the range of 0 to 30 ° with respect to the horizontal, washing is performed with the amount of water supplied minimized, and the washing water is heated with a small amount of water and a small amount of power consumption. Therefore, the temperature rise can be performed quickly, and a washing / drying machine excellent in cleaning performance and energy saving can be obtained.

  Moreover, since the heater 31 for heating is located in the bottom part of the water tank 3 and in the vicinity of the drain port 9, the water remaining in the vicinity of the drain port 9 by the heat is applied by energizing for a while after the drying step. Is heated and evaporated. Therefore, propagation of mold and the like when the washing / drying machine is not used can be suppressed, and a clean feeling can be maintained.

  Further, energization of the heater 31 may be controlled so as to reduce power consumption by de-energizing when the water temperature is relatively high, such as in summer. The control can be performed automatically or manually as is well known, and can be arbitrarily selected.

(Embodiment 2)
Next, a second embodiment of the present invention will be described. The second embodiment is a washing / drying machine in which the heat pump device 30 shown in FIG. 8 is incorporated in the circulation duct 15 in the configuration shown in the first embodiment.

FIG. 5 is a cross-sectional view at the time of washing and rinsing as seen from the side direction of the washing and drying machine in the second embodiment, and FIG. FIG. 7 is a cross-sectional view from the back of the washing / drying machine according to the second embodiment, with a part cut away. Furthermore, FIG. 8 is a conceptual diagram showing a system configuration of the washing and drying machine in the second embodiment. Constituent elements similar to those of the first embodiment are denoted by the same reference numerals and description thereof is omitted.

  The heat pump device 30 uses a flammable refrigerant that has little influence on the environment as the refrigerant, a vertical compressor 26 that compresses the refrigerant, a radiator 23 that radiates heat of the compressed refrigerant, and a pressure of the high-pressure refrigerant. A throttle means 27 comprising a throttle valve, a capillary tube, etc., for reducing the pressure, and a heat absorber 21 that draws heat from the surroundings by the reduced pressure and low pressure refrigerant are connected by a conduit 28 so that the refrigerant circulates. Then, the refrigerant flows and circulates in the direction indicated by the arrow h in FIG. 8 to realize a heat pump cycle.

  Here, the piping of the heat absorber 21 and the radiator 23 is seamless in order to suppress leakage of the combustible refrigerant into the circulation duct 15.

  And the heat radiator 23 and the heat absorber 21 are arrange | positioned through the radiator 23 and the predetermined space | interval in the position where the heat absorber 21 becomes an upwind side inside the circulation duct 15 which comprises the air blower 12. FIG.

  Further, the radiator 23 is disposed in the vicinity of the air supply port 15 b of the circulation duct 15, similarly to the heater 31.

  That is, the heater 31 and the radiator 23 are located in the vicinity of the drain port 9 formed at the bottom of the water tank 3 and are arranged so as to heat water remaining on the periphery of the drain port 9.

Next, the operation of the washing / drying machine having the above configuration will be described. In the second embodiment, since the drying process is different from that of the first embodiment, the description from the washing process to the dehydrating process will be omitted, and the drying process will be mainly described.

  In the drying process, the water supply valve 17 is closed with no current applied, the valve 32 and the heater 31 are energized, the air inlet 15b is opened as shown in FIG. 6, and the blower 12 is operated. Then, the compressor 26 of the heat pump device 30 is operated. Here, it is preferable that the heating temperature of the heater 31 is set to 360 ° C. or less below the ignition point because the refrigerant is a natural refrigerant.

  As a result, the refrigerant is compressed and circulates through the radiator 23, the throttle means 27, and the heat absorber 21 by this pressure.

  In the radiator 23, heat is released by the compression of the refrigerant, and in the heat absorber 21, the heat is absorbed by the refrigerant that has been decompressed by the expansion means 27 and becomes a low pressure. In parallel with this, the blower 12 is operated, and warm air heated by the heat radiation of the heater 31 and the radiator 23 is rotated from the air supply port 14 through the air supply port 15 b of the circulation duct 15 through the air supply path 20. Air is blown into the tank 5. The rotating tub 5 is rotationally driven by a drive motor 6 and the clothes 4 are stirred up and down.

  Therefore, the air in the circulation duct 15 is heated by the radiator 12 and the heater 31 by the blower 12 and blown into the rotary tank 5 from the air supply port 14. The warm air supplied into the rotating tub 5 takes moisture when passing through the gaps in the clothing 4, passes through the blower 12 from the suction port 15 a of the circulation duct 15 through the exhaust port 16 of the water tub 3 in the wet state, and absorbs heat. To vessel 21.

  When the wet warm air passes through the heat absorber 21, sensible heat and latent heat are removed, and the dehumidified air is separated into dry air and condensed water.

  When the dry air subsequently passes through the radiator 23, it is heated again by the radiator 23 to become warm air, further heated by the heater 31 for heating, and again from the air supply port 15b as shown by the arrow b. 3. It is supplied into the rotary tank 5, and the above-mentioned circulation is repeated thereafter.

  In the second embodiment, since the heat pump device 30 heats the drying air and removes moisture from the moist air, the drying performance is further improved as compared with the first embodiment.

  Furthermore, in the drying step, tap water is not used for moisture condensation of the wet air, so that the water saving effect can be enhanced. In addition, since the heater 31 and the radiator 23 heat the bottom of the water tank 3 in parallel with the air heating during the drying process, water remaining in the vicinity of the drain 9 can be quickly evaporated, By preventing the growth of mold and the like when the dryer is not in use, a clean feeling can be maintained.

  Further, a flammable refrigerant is used as the refrigerant, the surface temperature of the heater 31 is set to 360 ° C. or lower, which is lower than the ignition temperature of the flammable refrigerant, and the refrigerant is circulated to suppress leakage of the flammable refrigerant into the circulation duct 15. Since the refrigerant pipes of the radiator 23 and the heat absorber 21 provided in the duct 15 are seamless, the risk of ignition is low and high reliability can be obtained.

In the second embodiment, cleaning and rinsing water is heated only by the heater 31. However, the heat pump device 30 is operated when supplying water in the cleaning process and the rinsing process, and the radiator 23 is operated. It is also possible to perform heating by adding the heat radiation action.

In particular, the heat source of the heat pump device 30 at this time is the temperature (heat amount) of the air inside the washing / drying machine by the formation of the wind circuit 24 in which the heat absorber 21 exchanges heat with the air outside the washing / drying machine.

Therefore, the washing water and the rinsing water are efficiently cooled without being cooled by the heat absorber 21.

  In the drying process, the dampers 51, 52, 53, and 54 are maintained in the state shown in FIG. 10, and the blower 50 is in a stopped state.
